PROCESS OF LAYING- RAILWAYTRACKS.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 6, 1909. Serial No. 494,479.

To all whom it may concern:

Be it known that I, HENRY W. JACOBS, of Topeka, in the county of Shawnee and in the State of Kansas, have invented a certain new and useful Improvement in Processes of Laying Railway-Tracks, and do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to an improvement in methods of laying railway tracks.

The object of my invention is to enable tracks to be laid at a very much greater speed than can be accomplished at present, and to enable the laying to be effected very much more readily and with the expenditure of a minimum of labor.

In the accompanying drawings, I have shown two forms of railway track that might be laid bymy method, in which- Figure 1 is a vertical side view of a tie carrying rails held in place by the spikes such as are used by my method, showing the rails in section; Fig. 2 is a plan view of a railroad laid by my method; Fig. 3 is a plan view of a clip used in securing the spikes in place; Fig. 4 is a view of the underside of the same; Fig. 5 is a side elevation of the same; Fig. 6 is a cross-section of a railroad laid in a slightly diflerent manner; and Fig. 7 is a plan view of the same.

In the drawings 1 represents a series of ties carrying thereon a pair of rails 2, said rails being held in place by means of a number of spikes 3. Each of the spikes 3 comprises a screw-threaded shank 4: and a head 5. The head 5 of each spike consists of a squared portion 6 having located beneath the same a circular flange 7, having one side thereof flattened at 8. Each rail 2 is designed to be placed in position after the spikes have been inserted, the spikes being moved into the position shown to the left of Figs. 1 and 2. After the rail has been placed in position, a clip 9 may be placed uponeach spike, and the flattened sides 8 of the spikes, which have been before moved into a position adjacent to the edge of the rail, are then rotated 180 degrees until tight upon the clip and rail, as shown in Figs. 1 and 2. Each clip 9 as applied to the spikes comprises a flat portion 10 having a recess 11 therein to fit around the body of the spike beneath the circular flange 7, and a downwardly directed shoulder 13 to fit against the edge of the rail. After the s ikes have been rotated as above, a portion 0 each clip is bent upwardly against the flat face of the flange 7 so as to forma shoulder 12. The shoulder 12 prevents the spike from rotating, and .the shoulder 13 prevents the clip 9 from rotating.

I have shown a modification of my invention in Figs. 6 and 7, in which the spikes are shown as rotated only 90 degrees, in order to secure the rails in place. Practice has demonstrated that there is substantially no tendency whatever for the spikes to become I loosened in their sockets so as to become unscrewed and release the rail. I, therefore, find it advantageous in some instances to dispense with the clips and to rotate the screw spikes only 90 degrees, so that, subsequently, in case of wear to the ties, the spikes can be further rotated so as to draw the rails closer to the ties.

My invention is best carried out by drilling the holes for the spikes and inserting the spikes with the flat edges directed toward the position of the rail at a central plant, such as the finishing or treating plant for the ties. The spikes having been inserted in the proper position in the ties at the central plant, the spiked ties are conveyed to the point where the track is to be laid; they are then placed in position, tracks laid between the spikes, clips inserted if desired, the spikes rotated 180 degrees, and the shoulder 12 of the clips bent upwardly to prevent the spikes from rotating. The spikes may be, as stated, rotated only 90 degrees and the clips dispensed with, if found desirable.

In order to insure that the spikes will become tightened upon the rails at a predetermined position of the flattened sides 8 of the flanges of the spikes, the spikes are screwed into the ties by means of a screwdriving mechanism having a feed screw with a predetermined pitch equal to the pitch of the screw spikes and started into the drill holes with the flattened sides 8 in a predetermined position. By inserting the spikes in this manner, it can be determined with certainty that the spikes when tightened upon the rails, will have their flanges located an equal distance from the tops of the ties, and that the flattened sides of the flanges will be in the same relative positions to the edge of the rail.

While I have described my invention above in detail, I wish it to be understood that many changes may be made therein without departing fromthe spirit of my invention.

I claim V 1. The process of laying railroad track With wooden ties, which consists in boring holes in wooden ties by the use of hole positioning devices and at a point removed from the finallocation of the tie, screwing screw-spikes partly home in said holes, said spikes having cut-away heads, placing the tie in the position in which it is to be used, placing the rails in position on the ties and screwing the spikes home.

2. The process of laying railroad track with wooden ties, which consists in boring holes in wooden ties by the use of holepositioning devices and at a point removed from the final location of the tie, screwing screw-spikes partly home in said holes, said spikes having cut-away heads, placing the tie in the position in which it is to be used, placing the rails in position on the ties, placing a lock on each screwspike to prevent its retrograde rotation, and screwing the spikes home.

In testimony that I claim the foregoing I have hereunto set my hand.

HENRY W. JACOBS.
